Answer:
8.0
Step-by-step explanation:
The attached shows guesses until we have an answer accurate to 6 decimal places. Rounded to 1 decimal place, the answer is 8.0 years.
This (8 years) was our initial guess, based on the "rule of 72" which says the doubling time for 9% interest is 72/9 = 8 years.
Our second guess, at 8.1, was farther away from the doubled value, so the first guess at 8.0 is closer.
t = 8.0
Answer:
x² + y² = 34
Formula:
<u>Here find the radius using distance formula</u>: → origin : (0, 0)
<u>Thus the equation of circle</u>:
Answer:
Part 1)
Part 2)
Part 3)
Part 4)
Step-by-step explanation:
Part 1) Find the measure of arc AB
we know that
----> by central angle
we have
therefore
Part 2) Find the measure of arc ABC
we know that
The central angle of complete circle is equal to 360 degrees
so
Part 3) Find the measure of arc BAC
we know that
----> by angle addition postulate
we have
---> by central angle
---> by central angle
so
Part 4) Find the measure of arc ACB
we know that
The central angle of complete circle is equal to 360 degrees
so
substitute
